The study evaluated 10 accessions of linseed annonating and recording nine quantitative characters were recorded and annotated, viz., days to flowering (DTF), plant height in (cm) (H), primary branches (PB), secondary branches (SB), capsules per plant (CP), seeds per capsule (SC), plant stand (PS) and seed weight in (gms) (SW) and seed yield in (Kg/hectare) (YH). The evaluation of coefficient of variation phenotypic (PCV) and genotypic (GCV) indicated higher environmental impact revealed degree of differences in both the estimates in case of days to flowering (DTF), height (H), seeds per capsule (SC), primary branches per plant (PB), plant stand (PS), seed weight (SW) and seed yield hectare (SYH) (Kg per hectare). The PCV and GCV were highest for secondary branches with value of (33.16 ,32.39) whereas minimal value for days to flowering (DTF) (0.64,1) and seed weight(gm) (4.27,3.24). The role of additive gene action was suggested by high heritability linked with high genetic advance for capsules per plant (CP) (99.49,30.25) and secondary branches per plant (95.40,65.17). The relationship of seed yield with other components viz., high secondary branches and higher capsules per plant and moderate values for seed weight in grams (gm) and height (cm) is basis of selection criteria based on the formulation of breeding programs. The estimates of heritability were highest for capsules (99.27%) and secondary branches (97.41%) and minimum for seeds per capsule (SC) (38.37%). Likewise, highest genetic advance mean percentage was for secondary branches and lowest for days to flowering (DTF). The highest heritability for the traits like capsules per plant (CP) and secondary branches give a positive response to the selection. Traits with high (heritability) h2 as well as genetic advance (GA) are under the control of additive genes hence, these can be improved by selection based on phenotypic performance. Invariably higher PCV as compared to GCV indicated the role of environment in the manifestation of the traits. The positive and substantial genotypic and phenotypic correlation were for days to flowering (DTF) via height (H), capsules per plant (CP) via plant stand, primary branches genotypically and negatively are important with seed weight and positively yield per hectare (YH)(Kg/hectare). Height (cm), capsules per plant (CP), secondary branches and plant stand showed major positive direct effect. The information about yield improvement is associated with yield components which is essential for the formulation of breeding programs.
